Saft wins major order to supply battery systems for Shanghai Metro Line 10 trains

The new Shanghai Metro Line 10 trains will rely on Saft MATRICS MRX rail batteries for onboard backup power

Saft, the world specialist in the design and manufacture of high-tech batteries for industry, has continued its growing penetration within the Chinese market by winning an order for onboard battery systems for new trains currently under construction for the Shanghai Metro Line 10.

Saft will supply the onboard battery systems for power backup duties on a total of 38 trains. Shanghai Metro Line 10 is being constructed ahead of the Universal Exhibition, which opens in Shanghai in May 2010. It will be 36 km long, linking the district of New Jianwan Town, in the north, with Hongqiao airport to the south-east. Serving 31 stations it will be the first fully automatic high-capacity metro line to be opened in China.

The battery systems, based on Saft’s specialised MATRICS MRX nickel-cadmium (Ni-Cd) rail batteries, will provide reliable backup power to support emergency lighting, air conditioning, door operation and communication systems for the Metro trains in the event of an interruption to the main power supply.

Four Saft battery systems, each comprising 84 MRX100 cells, will be installed on each six-carriage SHL 10 trainset.

Olivier Amiel, General Manager of Saft in China, said: “This latest order for the Shanghai Metro Line 10, which follows other recent orders for metros in Beijing and Nanjing, is further proof of Saft’s leadership position in global metro applications as well our increasing penetration in the Chinese market. The key factors in this success are advanced battery technology, combined with high levels of service and support and crucially, the local backup offered through our manufacturing operation in Zhuhai.”

MRX batteries

Saft MATRICS MRX batteries are the ideal choice for this type of metro application as they have been purpose-designed to deliver maximum performance, reliability and low TCO (Total Cost of Ownership). They provide the low maintenance and long service life benefits of sintered/PBE technology within a slim, light-weight block battery package that shows a major size and volume advantage compared with conventional batteries.

The MATRICS MRX design is extremely reliable and does not suffer from the ‘sudden death’ which can affect some batteries, even in extreme temperatures ranging from -30° to +70°C.

Background on the Shanghai Metro

Operated by the Shanghai Shentong Metro Group, the Shanghai Metro opened in 1995. Since then, it has become one of the most modern and fastest-growing rapid transit systems in the world. Today, there are eight metro lines, 162 stations and 225 km of track in operation, making it the longest network in China. Daily ridership averaged 2.19 million in 2007 and set a record of 3.82 million on April 30, 2008. By the end of 2010, with new lines coming into service, the Metro will reach over 500 km.
